SIS(4) FreeBSD Kernel Interfaces Manual SIS(4)
NAMEsis -- SiS 900, SiS 7016 and NS DP83815/DP83816 Fast Ethernet device
driver
SYNOPSIS
To compile this driver into the kernel, place the following lines in your
kernel configuration file:
devicemiibusdevicesis
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
if_sis_load="YES"
DESCRIPTION
The sis driver provides support for PCI Ethernet adapters and embedded
controllers based on the Silicon Integrated Systems SiS 900 and SiS 7016
Fast Ethernet controller chips.
This driver also supports adapters based on the National Semiconductor
DP83815 (MacPhyter) and DP83816 PCI Ethernet controller chip.
The SiS 900 is a 100Mbps Ethernet MAC and MII-compliant transceiver in a
single package. It uses a bus master DMA and a scatter/gather descriptor
scheme. The SiS 7016 is similar to the SiS 900 except that it has no
internal PHY, requiring instead an external transceiver to be attached to
its MII interface. The SiS 900 and SiS 7016 both have a 128-bit multi-
cast hash filter and a single perfect filter entry for the station
address.
The NS DP83815 is also a 100Mbps Ethernet MAC with integrated PHY. The
NatSemi chip and the SiS 900 share many of the same features and a fairly
similar programming interface, hence both chips are supported by the same
driver.
The sis driver supports the following media types:
autoselect Enable autoselection of the media type and options. The
user can manually override the autoselected mode by adding
media options to rc.conf(5).
10baseT/UTP Set 10Mbps operation. The ifconfig(8)mediaopt option can
also be used to select either `full-duplex' or `half-duplex'
modes.
100baseTX Set 100Mbps (Fast Ethernet) operation. The ifconfig(8)mediaopt option can also be used to select either
`full-duplex' or `half-duplex' modes.
The sis driver supports the following media options:
full-duplex Force full duplex operation
half-duplex Force half duplex operation.
For more information on configuring this device, see ifconfig(8).
HARDWARE

+o @Nifty FNECHARD IFC USUP-TX
+o MELCO LGY-PCI-TXC
+o Netgear FA311-TX (DP83815)
+o Netgear FA312-TX (DP83815)
+o SiS 630, 635, and 735 motherboard chipsets
+o Soekris Engineering net45xx, net48xx, lan1621, and lan1641
DIAGNOSTICSsis%d:couldn'tmapports/memory A fatal initialization error has
occurred.
sis%d:couldn'tmapinterrupt A fatal initialization error has occurred.
sis%d:watchdogtimeout The device has stopped responding to the net-
work, or there is a problem with the network connection (e.g. a cable
fault).
sis%d:nomemoryforrxlist The driver failed to allocate an mbuf for
the receiver ring.
sis%d:nomemoryfortxlist The driver failed to allocate an mbuf for
the transmitter ring when allocating a pad buffer or collapsing an mbuf
chain into a cluster.
sis%d:chipisinD3powerstate--settingtoD0 This message applies
only to adapters which support power management. Some operating systems
place the controller in low power mode when shutting down, and some PCI
BIOSes fail to bring the chip out of this state before configuring it.
The controller loses all of its PCI configuration in the D3 state, so if
the BIOS does not set it back to full power mode in time, it will not be
able to configure it correctly. The driver tries to detect this condi-
tion and bring the adapter back to the D0 (full power) state, but this
may not be enough to return the driver to a fully operational condition.
If you see this message at boot time and the driver fails to attach the
device as a network interface, you will have to perform a warm boot to
have the device properly configured.
Note that this condition only occurs when warm booting from another oper-
ating system. If you power down your system prior to booting FreeBSD,
the card should be configured correctly.
